An estimate for √123 is.
A.10
B.11
C.12
D.13
Is the answer B?
Correct.
Yes, B is the answer.
The square root of 123 is 11.09053650640941716205160010261. This can be rounded to 11.1, which is close enough to 11. So therefore, B is the correct answer.
I hope this helps! :)
To estimate the value of √123, you can use a few different methods. One common approach is to find the two perfect square numbers between which 123 lies and then approximate the square root based on their values.
In this case, you can see that 11^2 = 121 and 12^2 = 144. Since 123 falls between these two perfect squares, the square root of 123 will be slightly greater than 11 but less than 12.
Therefore, the answer is C.12.
